Comparison of the Efficacy between Pemetrexed plus Platinum and Non-Pemetrexed plus Platinum as First-Line Treatment in Patients with Wild-Type Epidermal Growth Factor Receptor Nonsquamous Non-Small Cell Lung Cancer: A Retrospective Analysis

Research output: Contribution to journalArticle

Abstract

METHODS: We retrospectively analyzed the efficacy of various platinum doublet regimens as first-line treatments. Between 2007 and 2013, a total of 165 patients with wild-type EGFR nonsquamous NSCLC were included in this study.

BACKGROUND: Despite the development of molecular research and targeted therapy, patients with wild-type epidermal growth factor receptor (EGFR) non-small cell lung cancer (NSCLC) still receive platinum doublet chemotherapy as the standard first-line treatment. We investigated the efficacy of first-line regimens in patients with wild-type EGFR nonsquamous NSCLC.

RESULTS: Seventy-one (43.0%) patients were treated with pemetrexed plus platinum (PP) and 94 (57.0%) with non-pemetrexed plus platinum (NPP). The overall response rate was not different between the PP- and NPP-treated groups (26.8 vs. 28.7%, respectively; p = 0.78). The median progression-free survival (PFS) and overall survival (OS) also showed no differences between the two treatment groups (p = 0.12 for PFS, p = 0.42 for OS). The median PFS and OS for the PP group were 4.6 months (95% CI, 3.8-5.4) and 18.7 months (95% CI, 11.7-25.8), respectively, and for the NPP group, they were 4.2 months (95% CI, 3.4-5.0) and 12.2 months (95% CI, 10.3-14.1), respectively. In the subgroup analysis, most subgroups showed no significant difference in PFS and OS between the two treatment groups.

CONCLUSION: Our data showed that the efficacy of various platinum doublet regimens was similar in patients with wild-type EGFR nonsquamous NSCLC.
